< Feedback on Twitter hide content warning crap
This must be a selective roll-out by twitter, because I don't see this change myself. For now, as an alternative to viewing timelines and tweets without logging in, you could use nitter: https://nitter.poast.org/
Sensitive content warning has since changed to an "Age-restricted Adult Content" notice that requires a log-in to view the tweet. Script doesn't remove notices.
